How much remains undetected? Probability of molecular detection of human <em>Plasmodia</em> in the field (Publications)
BACKGROUND: In malaria endemic areas, most people are simultaneously infected with different parasite clones. Detection of individual clones is hampered when their densities fluctuate around the detection [...] trials. This study aimed at measuring the detectability of individual P. falciparum and P. vivax parasite clones in consecutive samples of the same patient and at investigating the impact of sampling strategies
Interpreting malaria age-prevalence and incidence curves: a simulation study of the effects of different types of heterogeneity (Publications)

The effects on age-curves for parasite prevalence, uncomplicated and severe episodes, direct and indirect mortality and first-line treatments [...] fever thresholds. Transmission heterogeneity affected the age-curves for all outcomes. The peak parasite prevalence was reduced and all age-incidence curves crossed those of the reference scenario with

Understanding the complex interactions between these parasitic infections is of public health relevance considering that control measures targeting malaria and [...] lower odds of hookworm infection, whilst a significant positive association was found between both parasitic infections in 6- to 8-year-old children. Coinfected children had lower odds of anemia and iron
Isolation of <em>Trypanosoma brucei gambiense</em> from cured and relapsed sleeping sickness patients and adaptation to laboratory mice (Publications)
y to melarsoprol is responsible for these high relapse rates. Therefore we aimed to establish a parasite collection isolated from cured as well as from relapsed patients for downstream comparative drug [...] relapsing during the 24 months follow-up, the same specimens were collected. Specimens with confirmed parasite presence were frozen in liquid nitrogen in a mixture of Triladyl, egg yolk and phosphate buffered
Malaria vaccines: from the laboratory to the field (Publications)

A malaria vaccine that can reduce the burden of disease in
Development of emodepside as a possible adulticidal treatment for human onchocerciasis-the fruit of a successful industrial-academic collaboration (Publications)
y sterilize adult worms. Emodepside is a broad-spectrum anthelmintic used for the treatment of parasitic nematodes in cats and dogs (Profender and Procox). Our current knowledge of the pharmacology of [...] l activity has been demonstrated in various models, including Onchocerca ochengi in cattle, the parasite most closely related to O. volvulus. Emodepside has now successfully passed Phase I clinical trials

Cloning of the repertoire of individual <em>Plasmodium falciparum</em> var genes using Transformation Associated Recombination (TAR) (Publications)
One of the major virulence factors of the malaria causing parasite is the Plasmodium falciparum encoded erythrocyte membrane protein 1 (PfEMP1). It is translocated to It the membrane of infected erythrocytes [...] from approximately 60 var genes in a mutually exclusive manner. Switching of var genes allows the parasite to alter functional and antigenic properties of infected erythrocytes, to escape the immune defense
